THE REASONABLE SELECTION OF FILTERING GRADIENT IN VIBRATION MEAS UREMENTS OF CIVIL ENGINEERING

HUAYJG Zhen-ping, CHENG Jian-wei (Institute of Engineering Mechanics, China Seismological Bureau, Harbin 150080, China)  
At prestnt, the resisting mixture filter with high gradient is used to avoid the frequency from folding-effect mixed in engineering vibration measurement. In this paper, the factors of influencing filtering gradient are discussed and the reasonable filtering gradients in measurement of various parameters are put forward.
